JAMA:Praliciguat对保留射血分数的心力衰竭患者峰值摄氧量的影响

对于保留射血分数的心力衰竭患者,可溶性鸟苷酸环化酶刺激剂Praliciguat不能改善患者峰值摄氧量

一氧化氮(NO)在保留射血分数的心力衰竭(HFpEF)的病理过程中发挥重要作用,近日研究人员考察了口服可溶性鸟苷酸环化酶刺激剂Praliciguat对HFpEF患者的疗效。
 
CAPACITY HFpEF是一项随机、双盲、安慰剂对照的II期试验,总计196名心力衰竭患者参与,患者射血分数至少为40%,峰值摄氧量降低(峰值Vo2),同时存在至少2种与一氧化氮缺乏相关的疾病(如糖尿病、高血压、肥胖或高龄)。随机将患者分为3个Praliciguat剂量组或安慰剂组,本次研究主要集中在40mg Praliciguat剂量组(n=91)与安慰剂(n=90)的比较研究上,为期12周。研究的主要终点为峰值Vo2与基线相比的变化。次要终点包括6分钟步行测试距离和通气效率与基线的变化。主要不良事件终点是因治疗引起的不良事件(TEAEs)的发生率。
 
在181名患者参与研究,平均年龄70岁,女性占41%,155名(86%)患者完成了试验。在安慰剂(n=78)和40mg Praliciguat(n=65)组中,Vo2峰值的变化分别为0.04mL/kg/min和-0.26mL/kg/min,安慰剂调整后,治疗组与基线检查相比差异为-0.30 mL/kg/min。预先指定的次要终点均无统计学意义。在安慰剂组和Praliciguat组,6分钟步行测试距离的变化分别为58.1米和41.4米,组间通气效率的平均最小二乘法变化差异为-0.3。与安慰剂组相比,Praliciguat组头晕(9.9% vs1.1%)、低血压(8.8% vs 0%)和头痛(11 % vs 6.7%)等TEAEs发生率较高。组间严重TEAEs的发生率相似(10% vs 11%)。
 
II期临床研究显示,对于保留射血分数的心力衰竭患者,可溶性鸟苷酸环化酶刺激剂Praliciguat不能改善患者峰值摄氧量。
